Letters Patent No. 100.146. dated February 22, 1870.

IMPROVEMENT IN RAILWAY-CAR COUPLING-S.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern I Be it known that I, THOMAS R. HERD, of Allegheny'C/ity, in the county of Allegheny, and State of Pennsylvania, have invented certain new and useful Improvements in Oar-Couplings; and I do hereby declare that the following is a full, clear, and exact de scription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of thisspecification. Y

The nature of my invention consists in the construction of car-couplings, whereby railroad-cars may be coupled together automatically, as herein described.

In the accompanying drawings- Figure 1 is a sectional elevation of my invention.

Figure 2, a rear view of the same.

Letters of reference denote parts.

The body of. the coupling A is hollow, and is of the same construction as those heretofore in use.

In the inside of said body is a carriage, A, having one or more rollers or wheels-A, on the top and at the base thereof, soar-ranged that they will be between said carriage A and the upper and lower part of the main body of the said coupling A.

At or near the central part of said carriage A and lying longitudinally therewith, is a recess, B, having a A, and is attached in any suitable manner to the side of the coupling A, which is provided-with the ordinary pin R and link S.

A lug, T, is attached to the side of said couplingA,

to prevent the carriage A? from being forced through. too far.

ing on the step 0, The link S then, being pushed, forces back the carriage A, removing the step 0 from the pin, which falls through the link S, and the coupliugs are attached, the pin R being removed. By the action of the spring D the cari'iageA returns to its first position. l

Having thus described my invention, What I claim as new, and desire to secure by Let ters Patent, is-- g The coupling A, with the link '8 and pin It, in com:

bination withthe carriage A, recess B, spring 'B', rollers A,-"step G, and spring D, when constructed,

arranged, and operating substanti, lly as described, and for the purpose set forth.'

In testimony'that I claim the foregoing as my own, I aflix my signature in presence of two witnesses.

. THOS. R. HERD.
